Busch wrecked during practice at Kansas and had to go to a backup car. He then spun while running third on Lap 6 of the race.

Busch was running near the rear of the field, reporting that his car was “snappy loose,” when he spun again, this time pounding the wall and suffering a big collision with Logano.

Busch said throughout the race that he could not understand why his car was so loose. Busch has never scored a top-five finish at Kansas, one of his worst tracks.

“It’s Kansas, right?” he told his crew when asked what happened.

“It just spun out all on our own,” Busch told reporters after climbing from his car. “I just don’t know what to do at Kansas. … The car just snapped out from under me in every corner.”

Busch had climbed to third in points with his win last week at Texas, but will now drop in the standings.

Logano was ninth in points but likely will drop out of the top 10.

“It’s done,” Logano said of his car. “We hit really hard.”

The race was the second Cup event since Kansas repaved its 1.5-mile track and drivers had a tough time controlling their cars on the fast oval.

“This track is just so narrow right now. You can’t move around,” Logano said. “We were tight for the most part, trying to free it up, and then we put left sides on there and got really loose. I was trying to hold on for what we had and I think there were a lot of guys around us that did the same thing and were really loose.

“We weren’t having a good day as it was, but you don’t want to end up in the garage like this.”
